LEGO has announced the fifth CUUSOO set, and it is (drumroll please)...the Mars Science Laboratory Curiosity Rover! Sadly, the UCS Sandcrawler did not make the final cut but Team Jigsaw's Thinking With Portals! may still have a shot. You can check out the LEGO CUUSOO Blog post for more information. Despite the sadness, we can look forward to a great set that immortalizes the giant, sky-crane-lowered, SUV-sized rover that is exploring the red planet right now.
